Description

Discharge guide mechanism and vertical conveying device

Technical Field

The utility model belongs to the technical field of the perpendicular transportation and specifically relates to ejection of compact guiding mechanism and perpendicular conveyer.

Background

At present, the technical scheme adopted by the existing vertical transportation device is as follows: the lift plate is first hovered at a home position, articles are placed on the lift plate, the lift plate is driven up to and from a target height by a drive mechanism, the lift plate hovers at the target height, the articles on the lift plate are retrieved, and then the lift plate is driven down to the home position by the drive mechanism and maintained in a hovering state so as to place the next article on the lift plate hovering at the home position.

Chinese patent No. CN201810283977.7 discloses a coconut tapping machine, which also uses the above-mentioned prior vertical transportation device, as the operation principle of the penultimate paragraph of the description, "the slide block 18 jacks up the lifting plate 9 through the hinge rod 19 during the moving process, the lifting plate 9 vertically slides on the slide bar 20 through the block 21 at the corner, so that the coconut moves up and approaches to the two cutting blades 5, the two cutting blades 5 keep rotating at high speed under the operation of the rotating motor 2, and the coconut can be tapped when contacting the two cutting blades 5". In summary, the working process is that the lifting plate descends and hovers, coconuts are placed and fastened, the driving device drives the lifting plate to ascend to enable the opening mechanism to open the coconuts, then the lifting plate descends to the original position and hovers, the coconuts which are already opened and processed are taken out, and the coconuts to be processed next can be placed again.

The defects of the prior art are as follows: the lifting plate (or the lifting plate) needs to be hovered twice in one conveying process, namely when the lifting plate reaches the highest point, the lifting plate needs to be hovered to take out the object or the object to be processed in other processes; also, when the lift plate reaches the lowest point, it is necessary to hover over the lift plate to retrieve an item or place the next item to be lifted, processed, onto the lift plate. The time spent hovering is long due to the two hovers experienced, so the efficiency of the lifting device is low. If the lifting plate is fully automatic, two detection devices are needed, one detection device is used for detecting whether the object is taken away when the lifting plate reaches the highest point, and the signal can be transmitted to the driving device after the object is taken away, so that the driving device drives the lifting plate to descend; the other is used for detecting whether the object is placed on the lifting plate when the lifting plate reaches the lowest point, and the signal can be transmitted to the driving device after the object is placed on the lifting plate, so that the driving device drives the lifting plate to ascend. Obviously, the technical solution of the existing fully-automatic vertical transportation device needs more detection elements and signal feedback elements to realize its automatic function, and the procedure and principle of circuit control are complicated, which is not conducive to understanding and implementation by those skilled in the mechanical field.

EXAMPLE III

In order to solve prior art, perpendicular conveyer when the discharge gate ejection of compact, all need the problem of hovering when the material was got to the pan feeding mouth, this embodiment has given the perpendicular conveyer who solves this problem.

As shown in fig. 1 to 17, the vertical transportation device includes a lifting pallet 20, a driving device having a lifting portion for driving the lifting pallet 20 to lift in a lifting channel, and a discharge port at one side of an upper portion of the vertical transportation device, wherein a discharge guide mechanism 30 is disposed at the upper portion of the lifting channel, and the discharge guide mechanism 30 is used for supporting an object pushed up by the lifting pallet 20 to slide along the discharge guide mechanism 30 to the discharge port; the lower part of the lifting channel is fixedly provided with a feeding supporting plate 10, and the lifting supporting plate 20 is used for supporting objects on the feeding supporting plate 10 without interfering with the feeding supporting plate 10 when the lifting channel is lifted;

one side of the lifting supporting plate 20 is rotatably mounted on a lifting part of the driving device, a limiting abutting plate 201 is fixedly arranged at the lower part of the lifting supporting plate 20, and the limiting abutting plate 201 is used for abutting against the lifting part when the lifting supporting plate 20 is turned and unfolded downwards to be parallel to the feeding supporting plate 10 so that the lifting supporting plate 20 is not turned downwards any more; one side of the feeding supporting plate 10 is provided with a side bypass channel for the lifting supporting plate 20 to continuously descend after being turned over and retracted by abutting against the end of the object.

The vertical transport device has five states. In the first state, the lifting supporting plate 20 is initially arranged above the feeding supporting plate 10, and an object placed from a feeding port at the lower part of the vertical conveying device is placed on the feeding supporting plate 10; due to the existence of the limiting supporting plate, the lifting supporting plate 20 is in a state of being parallel to the feeding supporting plate 10 at the beginning; promote layer board 20 and contact with article upper portion under the drive of lifting unit, thereby promote layer board 20 and be supported by the article and take place the upset, along with lifting unit continues to descend, promote layer board 20 anticlockwise and has overturn and be close 90 degrees, be in the state of packing up. In the second state, the lifting pallet 20 moves along with the lifting part and moves to the bottom of the lifting channel through the side channel, at this time, because no object supports against the lifting pallet 20, the lifting pallet 20 turns clockwise under the action of its own gravity, and when the lifting pallet 20 turns and unfolds to a position parallel to the feeding pallet 10, the lifting pallet is prevented from continuing to turn clockwise by the limiting support plate 201, and the lifting pallet is kept at an angle parallel to the feeding pallet 10. In the third state, the lifting pallet 20 rises along with the lifting part, and since the shape of the supporting part is staggered with the shape of the feeding pallet 10, the lifting pallet can not interfere with the feeding pallet 10 during rising, and can support the object on the feeding pallet 10 to continuously rise when passing through the feeding pallet 10. In the fourth state, the lifting pallet 20 rises to the discharge port of the vertical transport device along with the lifting part, and the object is supported by the discharge guide mechanism 30. In the fifth state, the lifting pallet 20 continues to rise, and the articles slide along the discharge guide 30 toward the discharge port and are pushed out of the vertical transport device for the next process.

Further, the lifting supporting plate 20 and the feeding supporting plate 10 are two rake-shaped plates with opposite tooth parts, and the rake teeth of the two are staggered. As shown in FIG. 6, when the lift plate 20 is raised to the same height as the input plate 10, the teeth of the lift plate 20 may hold objects on the teeth of the input plate 10 without interfering with the input plate 10.

Further, there is not enough space left between the lifting pallet 20 and the inner wall of the lifting channel for the objects to fall down. Since the lifting blade 20 needs to be lifted, a gap is inevitably left between the lifting blade and the inner wall of the lifting channel, and the width of the gap needs to be small enough not to allow the objects to fall from the gap in order to prevent the objects from falling from the gap.

Further, the lifting support plate 20 is provided with rollers or balls for facilitating the objects to slide out of the discharge hole. The articles are placed on rollers or balls to facilitate sliding out of the discharge port when abutting against the discharge guide mechanism 30.

Because the limiting abutting plate 201 and the lifting pallet 20 are connected into a whole or manufactured integrally, when the lifting pallet 20 rotates, the limiting abutting plate 201 also rotates similarly. Therefore, when the lifting support plate 20 rotates in a retracting or expanding manner, the limiting abutting plate 201 rotates along the arc-shaped rotating surface of the pin body limiting part 211 until the limiting abutting plate 201 rotates to the lower abutting surface of the pin body limiting part 211, the limiting abutting plate 201 abuts against the lower abutting surface of the pin body limiting part 211, and at this time, the lifting support plate 20 cannot rotate continuously and is kept in a position parallel to the feeding support plate 10. It should be noted that the pivot pin 21 may be replaced by a hinge, a pin, or other mechanism that is conventional to those skilled in the art for achieving a rotatable connection.

As shown in fig. 12, the lifting portion is a mounting riser 24, one side of the lifting support plate 20 is rotatably mounted on the mounting riser 24, a pressing member 28 is disposed on the mounting riser 24, a locking groove is disposed on the pressing member 28, and a locking member 29 for locking with the locking groove is fixedly disposed on the lifting support plate 20. Initially, the fastener 29 and the fastening groove are loosened, when the lifting support plate 20 descends to be abutted against the object, the lifting support plate 20 is pushed by the object to rotate anticlockwise to be retracted, the fastener 29 approaches the fastening groove, then the fastener 29 is fastened with the fastening groove, when the lifting support plate 20 descends to the lower side of the feeding support plate 10, due to the limitation of the fastener 29 and the fastening groove, the lifting support plate 20 is kept as shown in fig. 12, namely, the lifting support plate is perpendicular to the mounting vertical plate 24 and is parallel to the feeding support plate 10, so that the object can be supported. When the lifting support plate 20 is lifted to the highest point, a pushing member for pushing the pressing member 28 to rotate and retract the fastening member 29 and the fastening groove is arranged, so that when the lifting support plate 20 is lifted to the highest point and an object is unloaded from the lifting support plate 20, the pressing member 28 is pushed by the pushing member and rotates and retracts, the fastening groove is separated from the fastening member 29 and returns to the initial state, the lifting support plate 20 returns to the free state, and when the lifting support plate 20 is lowered, the pressing member 28 is not interfered by the pushing member any more and can be ejected again. When the lifting plate 20 is lowered and again contacts the object, the catch 29 and the catch groove are again engaged.

Further, the discharging guide mechanism 30 is a plurality of guide pieces arranged at intervals, and each guide piece has an edge for guiding. The gaps are formed between every two guide sheets, so that fruits or other objects without flat surfaces can stably abut against the discharging guide mechanism 30 without sliding. Aiming at large-sized fruits such as watermelon and the like, the gap can be set to be larger, so that the arc-shaped part of the watermelon can be sunk into the middle of the gap, and the discharging guide mechanism 30 can stably guide the watermelon to prevent the watermelon from deviating laterally in the discharging process.

Furthermore, the guide piece is a triangular guide piece, and the edge is an inclined edge of the triangular guide piece.

Further, the edge is a blunt edge for protecting the object from being scratched.

Furthermore, an elastic gasket is arranged on the edge. The elastic gasket can be a buffer pad with a buffer function such as a sponge gasket or the like or a buffer pad for preventing objects from being crushed by the edges. The elastic gaskets can be respectively arranged on the edges, or the whole elastic gasket can be directly arranged on the guide surface formed by a plurality of edges.

Further, the driving device comprises a vertically arranged lead screw 52, and mounting supports 40 arranged at two ends of the lead screw 52 and used for positioning and mounting the lead screw 52, wherein a lead screw nut 50 is arranged on the lead screw 52, and the lead screw nut 50 is used for lifting when the driving device drives the lead screw 52 to rotate.

Further, the driving device includes a speed reducing motor 42 and a chain wheel transmission mechanism 41, wherein the chain wheel transmission mechanism 41 is used for transmitting the torque of the speed reducing motor 42 to the lead screw 52. It should be noted that the sprocket gear 41 includes a sprocket and a chain, and the sprocket gear 41 can be replaced by a pulley gear and other torque transmission mechanisms commonly used by those skilled in the art. Of course, the reduction motor 42 is only a preferred embodiment and may be replaced by an electric motor or other drive device that can provide torque. In order to protect the chain wheel transmission mechanism 41, prevent hard objects, oil stains, water drops and the like from entering the chain wheel transmission mechanism 41 and influencing the speed reducing motor 42 to transmit the torque to the screw rod 52, a protective cover can be arranged to cover the output end of the speed reducing motor 42, the upper part of the end part of the chain wheel transmission mechanism 41 and the end part of the screw rod 52, prevent the hard objects, the oil stains and the water drops from falling into the chain wheel transmission structure from the upper part, and prevent the influence on the normal operation or the damage to the chain wheel transmission structure.

Further, two sides of the lead screw 52 are respectively provided with a slide rail 51 and a slide block capable of sliding on the slide rail 51, two sides of the installation vertical plate 24 are respectively installed on the two slide blocks, and the installation vertical plate 24 is further fixedly connected with the lead screw nut 50. The slider plays the effect of supplementary fixed mounting riser 24, prevents that mounting riser 24 from taking place the sideslip at the in-process of going up and down.

Further, an upper sensing piece 22 is disposed on the upper portion of one side of the lifting portion, a lower sensing piece 12 is disposed on the lower portion, an upper photoelectric proximity switch 23 for detecting whether the upper sensing piece 22 passes through and feeding back a signal to the speed reduction motor 42 and a lower photoelectric proximity switch 11 for detecting whether the lower sensing piece 12 passes through and feeding back a signal to the speed reduction motor 42 are disposed on the slide rail 51 corresponding to the same side of the upper sensing piece 22 and the lower sensing piece 12. It should be noted that the optoelectronic proximity switch may be a correlation-type photoelectric sensor. When the lower photoelectric proximity switch 11 senses the lower sensing piece 12 or the upper photoelectric proximity switch 23 senses the upper sensing piece 22, the speed reduction motor 42 is stopped or reversed to control the lifting support plate 20 to hover or move reversely.

When the lower photoelectric proximity switch 11 detects that the lower sensing piece 12 passes through, signals are fed back to the speed reduction motor 42 and the buckling motor 61, the speed reduction motor 42 reversely rotates to control the lifting part to move upwards, the buckling motor 61 controls the buckling part 62 to synchronously extend out and tightly abut against the extension limiting plate 2001, and the extension limiting plate 2001 is locked.

Further, the lifting supporting plate 20 and the feeding supporting plate 10 are two rake-shaped plates with opposite tooth parts, and the rake teeth of the two are staggered. As shown in FIG. 6, when the lift plate 20 is raised to the same height as the input plate 10, the teeth of the lift plate 20 may hold objects on the teeth of the input plate 10 without interfering with the input plate 10.

Further, there is not enough space left between the lifting pallet 20 and the inner wall of the lifting channel for the objects to fall down. Since the lifting blade 20 needs to be lifted, a gap is inevitably left between the lifting blade and the inner wall of the lifting channel, and the width of the gap needs to be small enough not to allow the objects to fall from the gap in order to prevent the objects from falling from the gap.

Further, the lifting support plate 20 is provided with rollers or balls for facilitating the objects to slide out of the discharge hole. The articles are placed on rollers or balls to facilitate sliding out of the discharge port when abutting against the discharge guide mechanism 30.

Further, the feeding pallet 10 extends with a baffle 25 at one side of the corresponding side bypass channel for preventing the object from sliding into the side bypass channel. The baffle 25 is provided to better assist in locating the item and preventing it from falling.

Further, the discharging guide mechanism 30 is a plurality of guide pieces arranged at intervals, and each guide piece has an edge for guiding. The gaps are formed between every two guide sheets, so that fruits or other objects without flat surfaces can stably abut against the discharging guide mechanism 30 without sliding. Aiming at large-sized fruits such as watermelon and the like, the gap can be set to be larger, so that the arc-shaped part of the watermelon can be sunk into the middle of the gap, and the discharging guide mechanism 30 can stably guide the watermelon to prevent the watermelon from deviating laterally.

Furthermore, the guide piece is a triangular guide piece, and the edge is an inclined edge of the triangular guide piece.

Further, the edge is a blunt edge for protecting the object from being scratched.

Furthermore, an elastic gasket is arranged on the edge. The elastic gasket can be a buffer pad with a buffer function such as a sponge gasket or the like or a buffer pad for preventing objects from being crushed by the edges. The elastic gaskets can be respectively arranged on the inclined edges, or the whole elastic gasket can be directly arranged on the guide surface formed by a plurality of spaced edges.

Further, the lifting part is a mounting vertical plate 24, a rotating pin 21 is mounted on the mounting vertical plate 24, the rotating pin 21 comprises an arc-shaped rotating surface at the side part and an upper abutting surface, and the upper abutting surface is used for abutting against the extension limiting plate 2001. Since the extension restricting plate 2001 is integrally connected to or formed integrally with the lifting blade 20, the extension restricting plate 2001 also rotates when the lifting blade 20 rotates. Therefore, when the lifting blade 20 rotates in a retracting or expanding manner, the extension limiting plate 2001 rotates along the arc-shaped rotating surface of the pin body limiting member 211 until the extension limiting plate 2001 rotates to the upper abutting surface of the pin body limiting member 211, the extension limiting plate 2001 abuts against the upper abutting surface of the pin body limiting member 211, and at this time, the extension limiting plate 2001 cannot continue to rotate upwards and anticlockwise and is kept in a position parallel to the feeding blade 10. It should be noted that the pivot pin 21 may be replaced by a hinge, a pin, or other mechanism that is conventional to those skilled in the art for achieving a rotatable connection.

Further, the driving device comprises a vertically arranged lead screw 52, and mounting supports 40 arranged at two ends of the lead screw 52 and used for positioning and mounting the lead screw 52, wherein a lead screw nut 50 is arranged on the lead screw 52, and the lead screw nut 50 is used for lifting when the driving device drives the lead screw 52 to rotate.

Further, the driving device includes a speed reducing motor 42 and a chain wheel transmission mechanism 41, wherein the chain wheel transmission mechanism 41 is used for transmitting the torque of the speed reducing motor 42 to the lead screw 52. It should be noted that the sprocket gear 41 includes a sprocket and a chain, and the sprocket gear 41 can be replaced by a pulley gear and other torque transmission mechanisms commonly used by those skilled in the art. Of course, the reduction motor 42 is only a preferred embodiment and may be replaced by an electric motor or other drive device that provides torque. In order to protect the chain wheel transmission mechanism 41 and prevent hard objects, oil stains, water drops and the like from entering the chain wheel transmission mechanism 41 and influencing the speed reducing motor 42 to transmit the torque to the screw rod 52, a protective cage can be arranged to cover the output end of the speed reducing motor 42 and the upper parts of the chain wheel transmission mechanism 41 and the end part of the screw rod 52.

Further, the lifting portion is an installation vertical plate, two sides of the lead screw 52 are respectively provided with a slide rail 51 and a slide block capable of sliding on the slide rail 51, two sides of the installation vertical plate 24 are respectively provided with two slide blocks, and the installation vertical plate 24 is further fixedly connected with the lead screw nut 50. The slider plays the effect of supplementary fixed mounting riser 24, prevents that mounting riser 24 from taking place the sideslip at the in-process of going up and down.

Further, an upper sensing piece 22 is disposed on the upper portion of one side of the lifting portion, a lower sensing piece 12 is disposed on the lower portion, an upper photoelectric proximity switch 23 for detecting whether the upper sensing piece 22 passes through and feeding back a signal to the speed reduction motor 42 and a lower photoelectric proximity switch 11 for detecting whether the lower sensing piece 12 passes through and feeding back a signal to the speed reduction motor 42 are disposed on the slide rail 51 corresponding to the same side of the upper sensing piece 22 and the lower sensing piece 12. It should be noted that the optoelectronic proximity switch may be a correlation-type photoelectric sensor. When the lower photoelectric proximity switch 11 senses the lower sensing piece 12 or the upper photoelectric proximity switch 23 senses the upper sensing piece 22, the speed reduction motor 42 is stopped or reversed to suspend or reverse the lifting support plate 20. In addition, the position of the lower photoelectric proximity switch 11 should correspond to the position of the lower sensing piece 12 when the lifting support plate 20 abuts against the inner bottom wall of the lifting channel and turns upwards to be parallel to the feeding support plate 10, so that the lifting support plate 20 turns to be parallel to the feeding support plate 10 and the speed reduction motor 42 starts to turn backwards after the mechanical buckle device 60 locks the extension limiting plate 2001.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
